. WINDOW.

Application led June 22, 1925. Serial No. 38,905.

This invention relates to improvements in windows and has particular reference to a metallic window construction.

The object of the invention is to provlde an improved metallic window with sliding sashes wherein the window frame and sashes are so constructed and inter-engaged that when the window is in closed position, there will be insured two or more points vof contact, metal to metal, all around each sash, that is, at the head, the sill andthe two sides of the 4frame and at the meeting rail or rails of the sashes.

Another object of the invention is to provide an improved window wherein the Window frame and sashes are so constructed and interengaged that the same will eliectively preventl the ingress of air and dust into a room when the sashes are in closingposition.

A further object is the provision of an improved window in which the frame and sashes are so constructed and interengaged thatany rattling of the sashes, when closed, due to lateral movement thereof with respect to the frame, will be prevented.

A still furtherobject is to so construct the frames and sashes that the window may be readily and quickly assembled in operative position. 3o The above and other objects will appear more' clearly from the following detail description, when taken in connection with the accompanying drawings, which illustrate one embodiment of the inventive idea.

In the drawings- Figure 1 is a front elevation of a window constructedin accordancewith the invention;

Figure 2 is a fragmentary transversel section of ythe window showing both lsashes in cross section;

Figure 3- is a vertical'sectional view of the window with both sashes in closing position;

Figure 4Ais a perspective view of one of the stiles of the sashes;

Figure 5 is an enlarged ragmentary sectional view showing part of the head of the window illustrated in Figure 3 while the same is partially open.

The window is made of any desired material, such as steel or bronze, which is rolled or extruded to form the various parts of the window. 'Phe frame of the windowl com- `opposite sides of the partin prises the side, to and sill sections 5, 6, and

respectively. of which is illustrated in Figure 2, each comp rises the outer, intermediate and inner port1ons 8, 9 and 10 respectively, the intermediate portion being preferably integral with the adjacent outer and inner sections. Forming a part of the inner portions 10 is a stop or guide 12 secured to said portion b means of fasteners 13. Medially of its longltudinal edges, the intermediate portion 9 is provided with aparting strip 14 held in place by screws r other suitable means. On strip 14 there are provided wedge-shaped anges 15 which combine with the sides of the parting strip to form grooves 16 for the purpose which will hereinafter appear. The sides of the parting strip 14 are also formed with vertically disposed grooves 17 similar to grooves 18 formed in opposed surfaces of the portion 8 and the gulde 12. Y

The sill sectlon 7 is of channeled 'formation so. as to receive a suitable material 19 utilized to securel anchor said section in proper position with respect to the sill of. the window opening. Intermediate the edges ofthe section 7 the same is provided with an upwardly pro'ecting portion 20 having sides 21 and 22, t e former ci which coo rates with a wedge-shaped flange23 to orm a groove 24 for a Ipurpose which will appear The window further comprises the upper and lower sashes 25 and 26 which are practically identical in construction. The sashes 25 and 26 include stiles, generally indicated by the numeral 27, the upper and lower rails 28and 29 and the meeting rails 30 and 31. The Stiles 27 and the up r and lower rails 28 and 29 are substantlally alike in construction and each includes a web portion 32 (see Figure 4) having the flanges 33 extending from the longitudinal edges thereof in the same direction and in parallel relation. Formed Aintegrally with one of the flanges 33 and extendin from the inner face thereof and intermediate its longitudinal edges is a diagonally disposed flange 34 which combines with the outer portion of said lange 33 to form a substantlally V-shaped groove 35. The groove 35 of the upper rail 28 is designed to receive-one of the flanges 15 of e side sections, only onel in the course of the description. I

the intermediate portion 9 of the frame. The inner ortions of the anges 33 upon which'the anges 34 are formedl engage in the groove 16, thus forming a connection between .the sashes and frame. Furthermore, as the upper' sash is raised to a completely closed sition as illustrated in Figure 3, the s ace 15' of the wedge-shaped ange 15 will crowd the head of the sash in adirection at riglht angles to the plane of the window so t at the parts will assume the sition shown in Figure 3 when the winow is completely closed. By the time that the surfaces 15 and 15" have crowded the head of the sash over until the surface 14" enga es the surface 14', the surface 34 of the ange 34 will be engaging the surface 34" of the wedge 15. In this manner, a three point contact is piro-vided. This contact is continuous for t e full length of the ange 15. It will, therefore, be noted that a luralit of surface contactsare rovided w ich wil be in engagement for t eir full surface when the window is completely closed as shown in Figure 3. It will be noted that the V-shaped groove 35 and flange 15 are accurately matched to fit each other and the parts are so positioned that ordinarily the sash may be moved up and down freely but when t e parts are in their completely or exactly closed position, there will be a good contactbetween the variousA parts.

The flanges 38 and 39 of the lower rail 29 of the lower sash are of different widths and the flange 38 is provided with a flange 40 similar to the flanges 34 to form a groove for receivin the ange 23 when the lower sash is in c osed position.v The flange 40 then also engages ,in the groove 24 to form a contact between the lower rail and sill. The wedge-shaped flanges 23 and the V- shaped groove formed by fianges 38 and 40 are accurately matched so that when the lower sash is completely closed, the, parts will assume the position shown in Figure 3 and thereby produce a three point contact or three surfaces of contact for the full length 4of the sill. As the lower sash is moved to its full closed position illustrated in Figure 3, t e .flange 40 will engage the side 21 and, consequently, crowd or shift the lower part of the sash toward the left as shown in Figure 3 and thereby cause the ange 39 to=press firmly against the side 22. The sha and relative position of the iiange 38 and ange 23 will cause these two members to tightly engage at the same time as the above aotlon takes place.

From Figure 3 it will be noted that when the lower sash is completely closed, the surface 40 will be engaged by the surface 21 of side 21 and that there will .be a wedging action which will cause the contact surface 39 of flange 39 to press tightly against the -the sash is lowered 4to its fully closed positrated in Figure 3.

to locking position,

' is a smal contact surface 22. The action of the surfaces 21 and 40 in effect pulls the surfaces 39 against'the surface 22 while the surfaces 38 and 23 move into engagement as 'l0 tion. In view of this action and also the action at the to of the 'window as illustrated particular y in Figures 3 and 5, a plurality of contact surfaces are rovided and when the meeting rails are pu led together, the same effect will be produced between the sashes and the vertical flan es 15 whereby there will be a plurality o contact surfaces around the entire perimeter of each of the sashes, particularly as there are two contact surfaces at the meeting rails illus- The meeting rails 30 and 31 are provided with a well known locking device 51 of a type which when thrown simultaneously forces the upper sash upwardly` a short distance while it draws the meeting'rails 30 and 31 together' to eiect continuous contact of certain contact surfaces as illustrated in Figure 3. It will be noted that the adjacent edges of. the meeting rails are provided with flanges 42 and 43 which overlap and interengage as illustrated in Figure 3. The window is illustrated in the position when the lock 51 has been operated and the window completely or,l tightly closed. When this takes place, the two meeting rails yare pulled vtoward each other to produce a good contact over a plurality of surfaces not only with the `flanges 15 but also with the parts of 100 the meeting rails.

From Figure 3 it will be noted that the surface 43 is tightly pressing against the surface 43 while the surface 42 is pressing tightl against the surface 42 and there 10:,

lspace 30 between the anges 42 and 43. Thus with the upper rail 28 and the rail 30 of the upper sash 25 simultaneously forced inward in a lateral direction with respect to the frame, andat the same time the 110 meeting rail 31 and the lower rail 29 of the lower sash forced outward in a lateral direction with respect to the frame, all as hereinhefore explained, the inner flanges 33 of the stiles 27 of the upper sash 25 are also 115 simultaneously forced into face contact with the outer side of the parting strips 14, also effet-tin other contacts between the flanges 15 of tie side jambs of the frame and the anges 34 of the sash stile. The outer 12u flange 33 of the two stiles 27 of the lower sash are also forced into face contact with the inner side of the parting stri 1'4 by reasonof the crowding over of the liottom rail 29 as it engages the sill and also byreason of 125 the action of the lock 51 pulling the'meeting rails together. It, therefore, is evident that the complete closing and locking `ot' the sashes'efects two or more continuous contacts, metal to metal7l between the two 'sashes 130 vthe sill as well as head, the two sides and the meeting rails of the and the frame at the two sashes.

The `outer surfaces of the flanges 33 of the stiles 27 and upper rail 28 engage the sides of the parting `strip 14 and combine with the grooves 7 vtherein to form small air chambers which aid in preventing air passing around the sashes' into the interior of a room. In addition to the air chambers formed by the grooves 17 the outer flanges 33 of the stiles 27 and upper rail 28 combine with the grooves 18 in the 'members 8 and 12 to form other air chambers. Also the stiles 27 and-upper rail 28 combine with the sections 5 and 6.of, the frame to form the large air chambers 36. Adjacent to one of the longitudinal edges of the 'web portion 32 of each stile and upper rail another flange 37 extends in the opposite direction from the flanges 33 but in parallel relation thereto and this flange 37 is utilized in securing the pane of glass in the window sash, as clearly illustrated `in Figures 2 and" 3. lThe inner flange 39 of the lower rail overlaps the side 22 of the raised portion 20 and said lower i raising and lowering rail combines with the'sill section to form the air chamber 41 similarto the, chambers 36. Disposed on each side of the window and extending partially over the topthereof, are the casings 44, in whichl the parting strips 45 are disposed for dividing the casing counterweights' 47. for the sashes. The`intermediate portions 9 of the side sections of the frame may vbe provided, if desired, with rubber bumpers 48 supported by means of plates 49 and against which the lower sash may engage to prevent the window. The lowersash 26 is,V rovided with an operating handle 50 to faci itate the of the sash.
